Measuring Ranges Of The Analog Input Modules In S7 Format - Siemens SIMATIC ET 200iSP Operating Instructions Manual

The 11-, 12-, 13- and 15-bit resolutions + sign are shown in the following table. Each analog
value is entered left-justified in the ACCU. The bits marked with "x" are set to "0".

11+VZ
12+S
13+S
15+S
Note
This resolution does not apply for temperature values. The converted temperature values are
the result of a conversion in the analog electronic module.

Measuring ranges of the analog input modules in S7 format

Introduction
The tables in this section contain the digitized analog values for the measuring ranges of the
analog input modules.
The binary representation of the analog values is always the same, so these tables only
compare the measuring ranges and the units.
